¹ ^ r <Tbe: moist, especially for potted plants

The previous invention relates to a humidifier for potting soil, especially for potted plants, hackers etc. to maintain a controlled and constant humidity level.

We already know about humidifiers, e.g. from the French Patent specification Br. 1 576 4O4, which simultaneously distributes and dosing devices for liquid fertilizers and in which a capillary space is provided, which the surface tension of the liquid to be distributed use and those of the equilibrium or of the imbalance make use of between the atmospheric pressure and the internal pressure of the liquid container, the The central pillars alternately play the role of an air inlet and a liquid lock plays.

However, the construction allows this type of soil humidifier it is not possible to achieve a controlled humidification. Such humidifiers are namely formed by a tubular element that is inserted directly into the earth, for example a flower pot. The pipe element is then a separate one -Container for the liquid to be distributed connected. Regardless of the fact that this device is impractical, it is left to the discretion of the consumer, to insert the pipe element more or less deeply into the earth or more or less earth into the hole, for example to be filled in, which calls into question a perfectly regular soil humidification

The object of the present invention is to provide a regular To ensure moistening of the soil in pots or tubs and thus the recorded irregularities and to eliminate the disadvantages arising therefrom.

For this purpose, the invention brings an earth humidifier in proposal, which is characterized in that it has a container, the bottom of which is covered with a layer of capillary material "and which by a partition into a space for receiving the zn humidifying earth and a space for receiving a liquid vessel is divided, as well as by a closure member in the wall of the vessel closest to the bottom of the vessel, comprising a tablet of porous material resting against the bottom and the capillary opening at a point between the tablet and the interior of the vessel , '

Further details and features of the invention result from the following drawing in conjunction with the accompanying drawings. The drawings show:

BATH ORIGINAL

Pig. 1 shows in a sectional view a humidifier according to FIG the invention.

Pig. 2 shows another embodiment in section an earth humidifier according to the invention,

The earth humidifiers according to the invention are formed by a container 1 with a partition 2 for dividing two rooms 3 and A. I the earth immediately, while in the -lus f clock form according to Pig, 2 in the room 3 a flower pot 13 is set. In the space 4, a liquid container 5 is removably inserted.

This vessel 5 comprises a plug 6 with a central opening 7 and a seat at the outer end of this opening 7 for receiving a tablet 9 made of porous material.

A slot or a capillary opening 10 is formed laterally in the plug 6 perpendicular to the longitudinal axis of the plug, which slot connects the central opening 7 with the area around the plug.

A disk or plate 11 made of capillary material is inserted at the bottom of the container 1 and is in direct contact on the one hand with the porous tablet 9 and on the other hand with the soil in the space 3, as shown in FIG. In the pig's palle. 2 the plate is in contact on the one hand with the tablet 9 and on the other hand with a capillary element 12 which is inserted into the bottom hole of the flower pot 17. The plate 11 thus ensures a pleated air circulation between the vessel 5 and the earth.

The operation of the earth humidifier according to the invention is the following*

ORIGINAL. ■ - * -

The vessel filled with liquid is first closed with the stopper 6, which can also be referred to as the rule stopper. Then the vessel is turned upside down so that the stopper S is at the bottom. The opening 7 fills you with liquid and the porous tablet The capillary opening 10 is also filled with liquid, which thus forms a barrier against the entry of air / The vessel 5 is inserted into the Ep at 4 so that the tablet 9 rests on the plate 11 made of capillary material "The plate in turn is in contact with the earth. The earth" sucks in liquid via the plate from which finally so large that atmospheric air pushes the liquid in the capillary opening 10 and then clears the opening. As a result, air enters the vessel and pressure equalization occurs again it is restored, the capillary opening 10 fills again with liquid,

This process is repeated as long as the earth has reached the desired degree of moisture, that is, until the capillary spaces in the space, which are smaller or the same size as the capillary opening 10, are filled with liquid. At this point in time, the capillary suction in the earth is too weak to create a negative pressure in the vessel such that the surface tension of the bite in the capillary opening 10 is overcome. As a result, air can no longer penetrate into the vessel , · ■.

Since the liquid-air exchange is interrupted, there is no longer any liquid transport. The liquid ε-rst begins to circulate again when through the

Roots in the soil or a part of the liquid in the capillary spaces of the earth is consumed by evaporation.

By designing the cross-section of the capillary opening 10 in the plug 6 to be more or less large, one can thus set a desired degree of humidity for the earth and keep it constant.
